131262-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131262-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,6 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131262-31:
(8*1)+(7*3)+(6*1)+(5*2)+(4*6)+(3*2)+(2*3)+(1*1)=82
82 % 10 = 2
So 131262-31-2 is a valid CAS Registry Number.

Protection of allyl alcohols as acetals, addition of difluorocarbene and deprotection lead to gem-difluoro(hydroxymethyl)cyclopropanes (3 and 11). These can be converted to potential insecticides of the pyrethroid type (5,6,7 and 12).
